Hi,
I am new to HDF5 interface. Before We actually start coding, I would like to know some advise for
the solution we are looking for. This for users who has been using HDF5 interface for quite a long
time. Please find the enclosed pdf for detail description of the problem.

There's an 'h5copy' utility in the HDF5-1.8 distributions that copies
full hierarchies and compressed datasets without uncompressing them
(among other features :-). That should do what you want...

I read through your PDF and it looks like a reasonable application of
HDF5. There are users who are storing millions (or more) of elements
in a dataset, so scaling to meet your needs shouldn't be a problem.
Currently, all compound datatypes in HDF5 are stored in a dataset in
"interleaved" form, which could affect your access to the
information. (You can retrieve a single field from dataset elements,
but it's not currently as efficient as it would be if the fields were
stored separately)

Oh that would be fantastic. Is a stable release of this version planned any
time?
Thanks a lot,
Dominik

There's a 'beta5' snapshot on the ftp server (ftp.hdfgroup.uiuc.edu)
and we're planning on getting the final 1.8.0 release out in the next
couple of weeks (~mid-January).

Ei, a couple of weeks is around the corner. Do you plan to release the
fix for the H5Zregister() in combination with
the --with-default-api-version=v16 flag?
Also, do you plan to maintain the MSVC 7.1 compiler, right? In the
medium term it would also great if you can support MINGW in Win as
well.
Cheers,

I'll try, but there's some higher priority bugs on the list right
now...

I can't remember what Kent & Elena decided to do about this, I'll CC
them and they can reply.

I looked over your attachment, it looks like you are using renderman.
I am doing something similar with HDF5, but using FBX instead.
I have seen work using HDF5 instead of XML for MPEG7 as a way to manage complex annotation of video streams.
Since you are using text streams that have complex heterogeneous Hierarchical graphics, the datasets are restricted to 1D datasets.
Unless you can organize them differently and manage that through your own importer/exporter.
What advantage do you think HDF5 will provide in regard to your production pipeline?

We are maintaining MSVC 7.1 compiler for C only. We also keep the
current support level of MINGW.

Thanks for maintaining MSVC 7.1 for C. Also, what do you mean by
keeping the current support level of MINGW? By this, I understand that
there will still be some HDF5 modules that can't be compiled and that
you won't be publishing binaries for MINGW. Please, correct me if I'm
wrong.
